[CLOSED]Component.ref does not work anymore

[CLOSED]Component.ref does not work anymore

has the config option ref of class Component been removed?
In Ext 3.3 I used this technique to get a reference to a component quite frequently because it produces much more readable code.
Is this available in Ext 4.0 or will it come back?

i think ref was not a bad idea, however you had to know the level of the component.
There was already a discussion, and i hope to get something like referenced items in a component for easy assign.
Easy would be a wrapper for ComponentQuery like this.getChildComponent(selector) - i prefer such for better readability, and to be different from DOM queries. At the end it's also a kind of taste.
